    rod knock when warm, good oil pressure. just replace bearings?

    All I can really tell you is its not a spun bearing,,,,if the bearing was spun that motor would run like a bucket of bolts for a short while possibly destroying the crankshaft,,,metal fragments would go everywhere oil can go destroying every moving part,scoring up the cylinders and pretty much...

    Well im tellin ya there were no seals on the exhaust valve stems,,,,,some jackhole put my heads together that way prob causing the fouling plugs.

    84 suburban motor swap

    I replaced my radiator with a new one for about 100 bucks, not too expensive. But I would not ever go to electric fans. I wouldn't trust anything electric (wire) to go bad when im out in the desert somewhere when I could have the reliability of a belt driven fan. I looked at buying a 2007...

The first cylinder on the left hand side spark plug was totally fouled, caked over with something it didn't look like oil because it was dry but was told its oil fouled. And its only the one plug that looks that bad. I did install new...

    '91 Burb, bearing noise in serpentine system

    I've had 2 alternators go out in past 2 years. Well they really didn't go out just started squeaking. I don't know how your pulleys could be out of alignment because if there bolted on right they should be in alignment. I would think if theyre out of alignment somehow it would be obvious by...

    What should i replace on a NP241 rebuild

    I havent rebuilt one yet. When mine went out I picked up one from a truck someone was parting out and just swapped it out. It was pretty easy to swap out the tcase. I know you can buy a rebuild kit and I heard its pretty easy to tear one apart. You just really need a good set of snap ring...

    I would check the timing,,,Theres a wire plug in you have to disconnect before you set the timing at 0deg TDC,,,,Its worth it to check the timing,,,these GM TBI motors are a pain in the ass to diagnose but when theyre running good they really do run good. High idle could be your timing is too...
